Overview
13
The goal of this spreadsheet is to document all anti-satellite (ASAT) tests in space and any orbital debris created by those tests. Criteria for inclusion in this sheet are:

1) Test of a known ASAT system (either co-orbital or direct-ascent)
2) Test of a hit-to-kill missile defense system against a target above 100 km

A separate spreadsheet with the history of rendezvous and proximity operations NOT associated with a known ASAT program or test can be found here.

Information about ASAT tests is compiled from a wide variety of public and open sources. Information about cataloged debris objects is primarily derived from the public Space Track website maintained by the U.S. military.
